A stone to flesh spell does not actually change the golem’s structure but negates its damage reduction and immunity to magic for 1 full round.

Slow (Su)

A stone golem can use a slow effect, as the spell, as a free action once every 2 rounds. The effect has a range of 10 feet in a burst centered on the golem and a duration of 7 rounds, requiring a DC 17 Will save to negate. The save DC is Constitution-based.

A stone golem has a humanoid body made from stone, frequently stylized to suit its creator. For example, it might look like it is wearing armor, with a particular symbol carved on the breastplate, or have designs worked into the stone of its limbs. Its head is often carved to resemble a helmet or the head of some beast. While it may be sculpted to carry a stone shield or stone weapon such as a sword, these aesthetic choices do not affect its combat abilities.

Like most golems, a stone golem cannot speak and makes no sound other than the grinding of stone against stone when it moves. A stone golem is 9 feet tall and weighs around 2,000 pounds.

Stone Golem Construction

A stone golem’s body is chiseled from a single block of hard stone, such as granite, weighing at least 3,000 pounds. The stone must be of exceptional quality, and costs 5,000 gp.
